Yes, the major question if you know that it was working at some point.
In that case I can try to trace breaking commit and that will be
relatively easy. If not, I believe it can be an old issue and I may
try to debug till I hit the wall of my limited knowledge and finally
submit PR(s). Regarding a bit different behavior on apm -z (S3
suspend) on my board compared to yours, I think it can be related to
dual CPU nature of my board. Unfortunately I don't have any single C3
boards, only VIA Nano (though I can test that as well).
